Introduction/Purpose Develop an integrated geospatial

data management system.

Develop GIS automation tools to integrate MPO data for transportation planning.

Enable data sharing among MPO partners

TELUDE – multi-year $750,000 GIS enterprise

5

What is TELUDE?

Transportation Environmental and Land-Use Data Enterprise = TELUDE

Centralized repository for enterprise data

Decision support for transportation planning

Three parts of TELUDE Data warehouse Web based tools Desktop tools for data automation Maintenance strategy and protocol

6

Impetus & Rationale for TELUDE

Organizational and technical challenges in obtaining data for myriad of multidisciplinary geospatial data for MPO planning functions. Travel model MPO UrbanSim Land Use Integration

Model NEPA/Project planning (Purpose &

Need) Project prioritization Transportation plan Congestion Management Process Etc.

7

Impetus & Rationale for TELUDE Cont’d

Data that MPO collects is voluminous and sometimes inaccurate and not timely.

MPO is primary consumer of data and not a primary producer (e.g. tax assessor’s data).

MPO must comb through member agencies’ GIS to find different pieces of information.

MPO agencies lack organization of data sources.

Many data sources are duplicated. No authoritative sources for some

data.

8

Impetus & Rationale for TELUDE Cont’d

MPO boundary ≠ Model boundary ≠ air quality non-attainment area ≠ scenario boundary.

An attitude of “Data is King”
